PATENT IMPROVEMENT lN INDICATORS.

Specification forming part of Letters Patent No. 172,591, dated January25, 1876; application filed 1 June 22, 1875.

To all whom it may concern:

Be it known that I, FRIEDRICH SUMPF, of St. Louis, in the county ofLouis and State of Missouri, have invented a new and useful ImprovedIndicator, of which the following is a specification This invention isan improved device to be used in connection with playing billiards, itbeing to time the players; also, it being a register of prices forbilliard-playing, as well as prices to be paid for the sale of food,drinks, &c. The construction and operation of my improvements I will nowmore fully describe, reference being had to the accompanying drawing, ofwhich- Figure 1 is a front elevation, showing the time-indicator indotted lines, and the priceindicator in full lines, Fig. 2 being abottom plan of Fig. 1.

A is a suitable casing or housing to contain the operating mechanism.The casing has its face-plate provided with openings, as ordinarily, todisplay the figures in their order. The casing A I divide into twocompartments, B B, by the partition B (See Figs. 1 and 2.) In the onecompartment B is the time-register, in the other B is theprice-indicator.

The time-register I construct as follows: C G are wheels or rollers,formed to have the ratchets c 0 which run in opposite directions. (Seefigures.) In said ratchets engage springpawls 0 0 also operating inopposite directions. (See Fig. 2.) I mount the wheels 0 G loosely onashaft, 0 so that the same can be turned in opposite directions, inorder to revolve the wheels. Thus the turning of the shaft in onedirection carries one wheel with it, while the other is held stationaryby its spring, and vice versa as regards the opposite Wheel. The wheels0 G I provide to have on their periphery figures-that is, on the wheel 0are the figures from 1 to 12, to represent the hours of the day. Thewheel 0 has figures such as 5, 10, 850., ending with 60, which numbersindicate the minutes or fractions of hours.

The time-register, thus constructed and arranged, supposing the playbegins at 9.30, (half past nine,) the operator, to indicate this time,simply turns the wheel 0 so as to bring the number 9 before its openingfor inspection,

and likewise turns the wheel 0 to bring thefigure 30 before its opening,and thus 9.30 stands as registering the time the play began.

The price-indicator I construct as follows: D D are similar rollers,having ratchets (1 d, and mounted upon a shaft, 01 in the identicalmanner as those of O C before described. I1 is the spring-pawl engagingthe wheel D, while that of d, engaging the wheel D, forms part of avertical operating stem, E. (See Fig. 1.) The stem E can be operatedfrom the top by depressing it, and in doing so its pawl d will engagethe ratchet of the wheel D, and move it the distance of the ratchet,which brings the next number forward for display. The lower end of stemE connects to a spring, 6, Figs. 1 and 2, which returns said stem tooriginal position.

The figures on the wheels D D are such that those on D are 1, 2, 3,850., in regular order, ending with 13, and represent dollars, thefigures on the wheel D being from 5, 10, 15, 850., ending with 95,representing cents.

When, therefore, the wheel D has displayed cents up to 95 cents, and itnext should be a dollar, it requires that the wheel D should be sooperated as to keep account of the dollars. This result I accomplish inthis manner: The wheel D has a pin, 0, Figs. 1 and 2, which, at propertime, coming round, comes in contact with one end of a pivoted lever, 0which it raises. The other end of said lever engages one of the studs orpins 6 projecting from the wheel D, and carries said wheel the space ofa figure. When the first end of lever is disengaged from the pin 6 aspring, 0 (see dotted lines, Fig. 2,) throws said lever in originalposition for the next repeated operation.

The price-indicator can either be operated by depressing the stem E, orby the same key turning the shaft 61 By thus turning the shaft 51 withkey the price-indicator can be set as required more rapidly, to indicatethe beginning, when prices are to be kept registered, than by acontinued operation of the stem E for the same purpose.

What I claim is- 1. The Wheels D D, numbered as shown and described,ratchets d d, shaft d springpawls d 01 in combination with stem E, pin

0 pivoted lever 6 studs 0 and spring 0 all said parts being arranged soas to operate substantially as specified.

2. The pivot-lever 6 pin 0, studs a spring a, in combination with wheelsD D, as herein shown and described, by means whereof the price tobeeharged higher in denomination in dollars is indicated, as set forth.

In testimony of said invention Ihave hereunto set my hand.

FRIEDRICH SUMPF.
